A cavernous sinus dural arteriovenous fistula (CSdAVF) is an abnormal communication between the dural branches of the internal and external carotid arteries and the cavernous sinus. Transvenous embolization is the first choice to resolve CSdAVFs, and various venous access routes have been reported. However, transvenous embolization of a CSdAVF through a rare venous anastomosis between the facial and superficial temporal veins using a quadruple coaxial catheter system is scarce in the literature. A 30-year-old woman presented with a typical triad of CSdAVF that was supplied by the inferolateral and meningohypophyseal trunks and several dural branches of the external carotid artery. CSdAVF was solely draining through the right superior ophthalmic vein to the bilateral facial veins. The right facial vein had a rare anastomosis, with the superficial temporal vein terminating in the external jugular vein. Transvenous targeted embolization of CSdAVF was performed through the right superior ophthalmic vein. The rare anastomosis between the right superficial temporal vein and the right facial vein was used as the access route for CSdAVF. The quadruple coaxial catheter system was effective in overcoming the long and tortuous access route and stabilizing the movement of the microcatheter for target embolization. CSdAVF was successfully embolized with microcoils. This is the first report of a CSdAVF embolized via a rare anastomosis between the facial vein and the superficial temporal vein. A quadruple coaxial catheter system can overcome this unusual access route.
